The first method defines sample database by artificial operation, the second method builds one sample database and one potential sample database by the samples self- training method. Some potential geometric regions are obtained by using a simple fast Hough arithmetic.

同样通过简单的快速Hough算法获取一些潜在几何区域，用对二值图像的块匹配方法对潜在的矩形区域进行识别并把它分类变成几种比分板和广告块。

A contour tree has found many important applications in map generalization,terrain analysis,etc.with respect to generating contour tree,this paper has proposed a scan-line based method,this method translates intersection point pair of scan-line and contour line as range,explains containment relation between range as containment relation between contour lines,determines "one-many" direct containment relations between parent contour and child contour by this method.

中国科学院计算所，北京 100080摘要等高线树在地图的产生、地形分析等应用中具有较重要的应用。对于产生等高线树，提出了一种基于扫描线的方法，该方法把扫描线和等高线之间的交点对解释为区域，利用区域之间的包含关系对应等高线之间的包含关系，以这种方式来确定父等高线与子等高线之间的"一对多"直接包含关系。

In order to eliminate the shortcomings of onerousness of calculation and of too many memory spaces needed in the practical calculation of establishing the heat transfer mathematical model of flame furnace by the zone method,"furnace section imaginary area" zone method has been developed in this paper.

本文针对区域法在建立火焰炉热交换数学模型的实际计算中存在计算层次太多、占计算机内存太大的缺点，提出了"炉段假想面"区域法。

The main works include: 1. successfully observed the opalescence of critical methanol and the phase variation of PET degradation in methanol, studied the internal construction of PET in different stages of degradation, provided the conception of critical region and noncritical region of system in which PET and methanol participated.

主要内容如下： 1 实验观测了甲醇的临界乳光现象及PET在甲醇中降解的相态变化，同时研究了不同降解反应阶段PET内部结构特征，在本实验研究的范围内提出了PET在甲醇中的系统临界区域和非临界区域的概念。

It is important to realize the Pareto Optimality of credit allocation in regions.

帕累托式的信贷区域配置对协调区域经济增长有重要意义。

As regard to the orientation of Asian regional cooperation , we have heard many original views.

但是，与欧洲和北美区域合作相比，亚洲区域合作相对落后。

This is a result of weak crustal thermal flow action and strong structure deformation during early stage of orogeny.

论文摘要：新疆阿尔泰海西期造山带主要发育两期区域变质作用，第一期变质作用属于区域低温动力变质作用类型，以形成低绿片岩相矿物组合为特征，变质温度较低，而应力作用较强，是造山作用初期热流活动较弱，构造变形强烈环境下的产物。

The main purpose of this work is to develop the spectral methods associated with some orthogonal systems of polynomials in unbounded domains.

本文正是在这样的背景下提出了无界区域中的谱方法。这种解法是与无界区域中的正交多项式密切相关的。我们的研究由以下几部分组成：第二章，建立了Hermite多项式插值逼近。

The state in orthogonal region 0 is always entered first, then the state in region 1 and so on

正交区域0中的状态总是首先进入，然后进入区域1 的状态，等等

Something to be aware of, is that Windows 2000 will accept a region that has overlapping

什么要注意的是，Windows 2000将接受一个区域，该区域重叠

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
